Application .filed September which it appertains to make and use they same. reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form apart ot this specification. This invention relates Vto locks and is primarily intended for use in locking chains .for the spare tires of automobiles, but is not restricted to such use.

` The object of the'invention is the provision lot a small, simple and inexpensive lock of the character described, which is practically proof against breaking or unauthorized opening, and which engages a .chain in such a manner as to render it impossible for unauthorized persons to release it from the lock when the parts 'there-` of are in locked relation, except by breaking the lock or cutting the chain links,both ot which parts are hardened. to guard against such act-ion.

The invention is full described in the following; specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure l is a side elevation of the lock embodying the invention in-locking engagement with the ends of the chain, which is only Lt'ragmentarily shown. Fig. 2 is a cen tral longitudinal section of the lock in locking engagement with the chain, taken on the line 2-2 in Fig. A6. Fig. '3 is a fragmentary view of th-e lock with parts of the socket member and of the lock barrel broken` away. Fig. 4 is a central longitudinal section of the lock with the parts in locking position taken on the line 4-4 in Fig. 6. Fig. 5 is a side elevation of the lock with a part of the socket member broken away. Figs. 6 and 7 are sections on the lines 6-6 and 7 7', respectively, inFig. l, and Fig. 8 is a section on the line 8 8 in Fig. 2.

Referring to the drawings, 'l designates the socket member of the lock, 2 the stud 1, 1922. seriai No. 585,583.

member thereof for insertion into the socketV member, and 3 a chain sect1on,'one end of which is engaged to thejsocket member and theV other to the stud member of the lock, as hereinafter described. Y

The socket member 1 is of elongated form and has a socket 4, inthe present instance of cylindrical form, provided longitudinally therein, being open at one end of the member and having its bottom disposed adjacent to the opposite end of the member.

The stud member 2 is intended to releasably fit into the outer or open end portion of thesocket 4 and is provided at itsinner end with a diagonaly or cross groove 5 and adja-A cent to such end with a circumferential groove 6in communication with the ends of the groove 5. A lockingv pin 7 is provided on the inner wall of the socket member l adjacent to its outer or open end in position to pass through either end of the groove 5, when in register therewith, and into the locking groove 6 when the stud 2 is7inserted into the socket member. A relative turning of the members l and 2 from this inserting position will dispose the pin 7 within the groove 6 between the ends of the groove 5, thus preventing a withdrawal of the stud from the socket member until, of course, the stud has been again turned to place either end of the groove 5 in register with the pin 7.

rThe locking meansemployed, in the present instance, is of the cylinder lock type and includes a cylindrical barrel S which is set into the socket member through an opening 9k in one side thereof with its axis at right angles to the axis of the socket member, the loc-k being secured against removal from the socket member by a rhardened pin 10 which is inserted into a sideopening in the barrel 8 through a. registering opening in a side ot the socket member. pin is cut ott' flush with the outer side of the socketmember to prevent gripping of the pin to withdraw it from engagement with the barrel. .The cylinder memberll of the locking means is adapted to receive and be turned by a key 12, and a turning of the key within the lock effects a retraction of the bolt pinlB within the lock barrel, said pin being spring pressed to normally hold the same projected, as well Vunderstood in the construction of locking means of this The outer end of the side of thefbarrely 8 lengthwise of the socket membervin position to enter the groove of the; stud member at onev sidel of lthe stud member axis when the stud vmember has Vbeen Ainserted into the socket member and turned A'to plaoethe `groove in*v receiving register herewith. The pinsj and 13, ink thepresent v instance, are placed at an angle to each `other withy respectv tothe socl'retaxis so that when the pinf( is inj'engagement withthe vstud groovelc` it will be necessary to turn `lthe stud to* placefthe. pin 7 at a point therein intermediatethe endsof ,theV groove 5 when such, groove'is 1n receiving registerwith the pin 13. It isthus'evident thatthe engage,-

mentqofjthe ,pin 7" within the groove 6 ,vill prevent afwithdrawing ot the Vstud Vmember 2roni thesocketfmember 1, except whensuchlpinis in'regist'er with an end of the; groove 5, and ,that the engagement ci thebolt-pin'v13 within the groove 5 will prevent a .turning of the stud '2 to releasing position, thereby etfectually locking the stud and 'socket members together.

1Thebolt-pin 13 isv normally held in lprojected position by a spring and is retracted by a.k turninghof the key. liwhenfinserted in the cylinder' 11, as well* understood in the art. "Upon an insertion vof the stud 2 kinto the socket member it is Vturned to cause the pin? to find either endoii'the slot 5 to enter therethrough into the Ygroove 6, and the bolt-pin; 13 y is then bearingagainstv the end .offthef stud 2 ata sidefof .the groove 5 so v vthat an inward pressure on the stud to place i the groove 6 into, register,withl the pin 'T fao will cause a compression of the bolt-pin 13 against4 its spring. The studk is then turned tokmovethe reoeivingend ofthe groove 5 from!` the pin 7 and to place said` groove in receiving register with the bolt pin, which then springs outward therein, asshown in yThe chain 3`with which the lock is connected, hasa link at one end thereof inserted through a slot 16 in the closed end of vthe socket member 1 and apin 17 Visrinserted into Vthe link through vthe lock receivingopening 9 oi the socket, thelock barrel S'being removed from the socket for such purpose, and the linkis then drawn outward tof dispose the pin 171within the base por- `tion ofthey socket 4 crosswise of the slot 16 andlin engagement Vwith the -socket bottom to prevent a: withdrawal of theY rcha-in link `appa-rent'. It is evidentthat this provides a very ystrong and durable means for' connecting one end of thechain to the socketVV memy ber and4 preventspa disengagement of the two except by cutting a chain link in two which is rendered very diliicult by the hardened nature of the links, or by removing the lock barrel S from the socket, which is ren-V dered exceedingly difficult by reason ofthe Vmanner of engaging such parts by the hard-- ened pin 10.

The stud member 2 ot the lock is provided in its outer end, with respect to the socket member, with a recess 18 in which the link at the opposite end ot' the chain to. that engaged to the socket member 1, is insertedl a sufficient distance to permit a cross-pin 19 carried by the stud member to be inserted therethrough. The crosspin 19 is inserted through a cross opening 20 in the member 2, which opening intersects the recess 18. The pin 19 preterably terminates. at its ends flush with the sides of the stud member and is held therein by reason of a tight fit, or in any other suitable manner. locking engagement with the socket member 1 the pin is disposed within the socket i so that it is prevented from removal from the stud member by the socket walls, as shown in Fig. 2. 4

It is evident that I have provided aV simple and efficient means for locking the ends of a chain or other member together and that itis particularly adapted Jfor engaging and locking together the ends ot a chain. It is also evident that when the members 1 and 2 of the lock are in assembled orlocked relation the ends of the chain can only be disengaged from the respective members by cutting, which is rendered exceedingly ditficult by reason of the hardened nature of the chain links, and the members can only be released by the insertion and turning of a proper key 12 in the cylinder lock to withdraw the bolt-pin 13. f

The lock is exceedingly simple and inexpensive from a manufacturing standpoint as both members 1 and thereof may be easilymade and one end ot' the chain may be easily and quickly enga-ged to the socket member before mounting the locking barrel 8 therein, as is apparent, and the ether end of the chain may be easily and quickly en- W hen the stud member 2 is in gaged to the stud member 2 when removed from the socket member.

I ywish it understood that my invention is not limited to any specilic construction, arrangement or form of the parts, as it is Vcapable of` embodiment in numerous forms without.' departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,- y
